Diagramas complejos de salud en el trabajo: metodología para el estudio sistémico de los procesos laborales / Complex diagrams of health in the workplace: A methodology for the systemic study of work processes

El estudio de los procesos de trabajo es una tarea «compleja¼ que incluye el conocimiento exhaustivo y preciso de los riesgos y exigencia laborales ahí presentes. Dichos riesgos y exigencias son el resultado de cómo se relacionan los elementos fundamentales del proceso laboral que, al interactuar con el hombre que trabaja, pueden afectar su salud. La finalidad de estas líneas es mostrar una metodología de carácter etnográfico, para investigar los procesos de trabajo en las entidades productivas y plantear las acciones preventivas conducentes. Esta metodología está basada en la observación directa y en la experiencia obrera de los procesos laborales. Consta de tres instrumentos de recolección de información: 1) Diagramas de Flujo del Proceso de trabajo; 2) Descripción de los Diagramas de Flujo de los Procesos de Trabajo; y 3) Cuadros de Resumen de los Diagramas Complejos de Salud en el Trabajo. A partir de los datos que proporcionan los Cuadros de Resumen, se estructura un repertorio de recomendaciones para el centro laboral. En cuanto a la utilidad de esta metodología, ha sido ampliamente probada en diversos sectores económicos, como: agricultura, industrias extractivas, de la transformación y la construcción, así como de los servicios, ya sean micro, pequeñas, medianas o grandes empresas. En síntesis, es una herramienta que proporciona el conocimiento integral de los procesos de trabajo, de los riesgos y exigencias que de ahí se derivan, y suministra las medidas preventivas para eliminar o controlar los peligros que acechan a los trabajadores en sus labores(AU)

The study of work processes is a complex task that includes exhaustive and precise knowledge of the labor demands and risks in a given workplace. These risks and demands result from the relationship among the fundamental elements of the work process, whose interaction with a worker can affect his health. The purpose of this study is to show how an ethnographic methodology was used to investigate work processes in productive industry workplaces and propose appropriate preventive actions. The methodology is based on direct observation and workers' experience of work processes. It consists of three data collection instruments: 1) Work process flow charts; 2) description of the flow diagrams of the work processes; and 3) summary tables of complex diagrams of workplace health. Based on the data provided in the summary tables, a set of recommendations for the workplace was designed. This methodology has been widely tested in various economic sectors, such as agriculture; extractive, transformative, and construction industries; and services, whether in micro, small, medium, or large companies. In summary, this is a tool that provides integrated knowledge about work processes and the risks and demands inherent in them and provides preventive measures to eliminate or control dangers to workers(AU)

RD internationalization, domestic technology alliance, and innovation in emerging market.

Although R&D internationalization plays an important role in enterprises' globalization, few studies explore the mechanism of R&D internationalization and emerging market companies' innovation, or the relationship between R&D internationalization, domestic technology alliances and absorptive capacity. How does the R&D internationalization of emerging market enterprises affect the innovation of those enterprises? Under fierce market competition, do absorption capacity and domestic technology alliances have a significant impact on enterprise innovation? From the perspective of the knowledge-based view, this paper studies 185 enterprises undergoing R&D internationalization in China from 2012 to 2017, using high-dimensional Poisson fixed effects model, we use instrumental (HDFE IV) estimation to explain the impact of R&D internationalization on the innovation of the parent company and the mechanism behind it. The study finds that R&D internationalization positively promotes the parent company's innovation, and domestic technology alliances and absorptive capacity play a partial mediator role in R&D internationalization. In the face of fierce market competition, domestic technical alliances play a significant role in promoting enterprise innovation, while absorptive capacity plays a negative role in promoting enterprise innovation with the moderating effect of market competition.

Comparing Selected Life-History Traits of Black Soldier Fly (Diptera: Stratiomyidae) Larvae Produced in Industrial and Bench-Top-Sized Containers.

As global food demand is increasing along with human population growth, there is a greater need for alternative protein sources. Insect protein, especially the larvae of the black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), has become a key approach for solving this issue in part due to its ability to convert organic waste into insect biomass with minimal resource (e.g., land, water) requirements. However, most information utilized to develop industrial production of this species is reliant on data generated from laboratory-scaled studies. Unfortunately, scaling these data to an industrial level potentially is not linear resulting in over, or under, estimating production. In this study, we compared selected life-history traits of larval black soldier fly produced at benchtop (e.g., 1 liter container with 614 larvae) and industrial scales (e.g., 29.5 liter container inoculated with 10,000 larvae). Larvae were provided a single feeding (2 g/larva) in each treatment. Significant differences in the mean larval weight (24.7%), survivorship (-28.2%), and biomass conversion (-2.7%) were determined between benchtop and industrial treatments. These results indicate larval number and the associated container size are important factors to consider when designing a black soldier fly factory. Furthermore, caution should be taken when applying data from laboratory studies to industrial scale production systems as the values potentially are not linear.

A study of the layout planning of plant facility based on the timed Petri net and systematic layout planning.

The purpose of this research is to solve the problems of unreasonable layout of the production plant, disorder of the logistics process, and unbalanced production line in discrete manufacturing plants. By analyzing the production process and characteristics, the timed Petri net model is constructed according to the function and connection of each production unit, which is then used to generate a FlexSim simulation model of the production plant logistics system with a simulation software. Therewith the FlexSim simulation model is used to simulate the original layout of the plant, and to analyse the simulation data synthetically to put forward an improvement strategy. Combined with the use of the systematic layout planning method to analyze the overall layout of the plant and logistics relations, we infer the relevant drawings between the production units and determine the improved layout of the facilities. Finally, by comparing the before and after improvement simulation results, it is verified that the combination of timed Petri nets and systematic layout planning is effective to ameliorate the layout of the plant facilities and the logistics system. This method makes up for the factors that traditional methods have not considered, achieves the goal of reducing the cross circuitous route of the plant and the idle rate of equipment, and improving the efficiency of production.

The Rise of Shop Floor Ergonomics: A Personal Perspective.

OCCUPATIONAL APPLICATIONS Based on a 45-year career as a practitioner in industrial ergonomics, I offer in this paper a personal memoir on how ergonomics came to the shop floor in North America, involving ordinary workers in an early effort to prevent what was at the time an unknown problem - work-related Musculoskeletal Disorders. The actions included the beginning of a low-tech, practical improvement process that is still effective today. In total, the experience can provide encouragement to everybody to be confident in their ability when trying new endeavors and to remember that small initial steps can eventually lead to major change.

Industrial cryo-EM facility setup and management.

Cryo-electron microscopy (cryo-EM) has rapidly expanded with the introduction of direct electron detectors, improved image-processing software and automated image acquisition. Its recent adoption by industry, particularly in structure-based drug design, creates new requirements in terms of reliability, reproducibility and throughput. In 2016, Thermo Fisher Scientific (then FEI) partnered with the Medical Research Council Laboratory of Molecular Biology, the University of Cambridge Nanoscience Centre and five pharmaceutical companies [Astex Pharmaceuticals, AstraZeneca, GSK, Sosei Heptares and Union Chimique Belge (UCB)] to form the Cambridge Pharmaceutical Cryo-EM Consortium to share the risks of exploring cryo-EM for early-stage drug discovery. The Consortium expanded with a second Themo Scientific Krios Cryo-EM at the University of Cambridge Department of Materials Science and Metallurgy. Several Consortium members have set up in-house facilities, and a full service cryo-EM facility with Krios and Glacios has been created with the Electron Bio-Imaging Centre for Industry (eBIC for Industry) at Diamond Light Source (DLS), UK. This paper will cover the lessons learned during the setting up of these facilities, including two Consortium Krios microscopes and preparation laboratories, several Glacios microscopes at Consortium member sites, and a Krios and Glacios at eBIC for Industry, regarding site evaluation and selection for high-resolution cryo-EM microscopes, the installation process, scheduling, the operation and maintenance of the microscopes and preparation laboratories, and image processing.

An individualized mental health education programme for Japanese managers.

BACKGROUND: Mental health education for managers has typically been conducted using a group format. Few studies have examined the provision of individualized education. AIMS: This study discussed the evaluations and characteristic needs of participants in an individualized mental health education programme while examining avenues for providing such education. METHODS: Eighty-nine individualized education sessions were conducted for managers (87 males, 2 females) with a mean age of 42.6 years (SD = 5.1) at an assembly factory in Japan. Data from anonymous self-administered questionnaires completed before and after the education programme were analysed. RESULTS: Overall, 95% of the managers (81/85) approved the individualized education format. The characteristic needs of participants with high motivation (45%, 38/85) were mental health consultations for managers (37%, 14/38, 95% confidence interval [CI] 1.62-14.7, P < 0.01) and subordinate-related concerns (18%, 7/38, 95% CI 1.11-22.8, P < 0.05). CONCLUSIONS: Individualized education may be a suitable method for conducting mental health consultations. It is recommended that the introduction of individualized education formats be implemented through voluntary consultations following group education. Individualized education may contribute to early intervention for work-related mental disorders.

Sufferings in silence: Violence against female workers in the ready-made garment industry in Bangladesh: A qualitative exploration.

INTRODUCTION: Despite the improved safety of the ready-made garment industry in Bangladesh since 2013, other workplace health and safety issues in the ready-made garment industry continue, especially violence towards female workers. This article examines this violence as well as the social norms and attitudes of key stakeholders underpinning it. METHODS: Data were collected in four ready-made garment factories in Bangladesh through in-depth interviews, focus group discussions with female workers and key-informant interviews with different stakeholders, along with factory observations. RESULTS: Findings were analysed thematically. Female workers described personal experience of violence in the workplace: physical and verbal abuse, constant pressure, other personal restrictions and withholding of pay. They did not make complaints for fear of losing their jobs. Supervisors characterized the women as 'disobedient,' 'uncooperative' and 'unwilling' to work and viewed their behaviour as acceptable. Other stakeholders ignored these problems. CONCLUSION: Finally, this study suggests how the findings encourage action to prevent violence in the workplace in order to address the emerging occupational health problems in Bangladesh.

Cell and gene therapy manufacturing capabilities in Australia and New Zealand.

Cell and gene therapy products are rapidly being integrated into mainstream medicine. Developing global capability will facilitate broad access to these novel therapeutics. An initial step toward achieving this goal is to understand cell and gene therapy manufacturing capability in each region. We conducted an academic survey in 2018 to assess cell and gene therapy manufacturing capacity in Australia and New Zealand. We examined the following: the number and types of cell therapy manufacturing facilities; the number of projects, parallel processes and clinical trials; the types of products; and the manufacturing and quality staffing levels. It was found that Australia and New Zealand provide diverse facilities for cell therapy manufacturing, infrastructure and capability. Further investment and development will enable both countries to make important decisions to meet the growing need for cell and gene therapy and regenerative medicine in the region.

Valuation of Estimation Toxic Chemical Release Inventory Method-Focusing on Paint Manufacturing Process.

Industrial chemicals differ in their treatment methods and types, depending on their physicochemical properties. Highly volatile chemicals are emitted despite installation of preventive facilities, such as scrubbers and adsorption towers. Some countries release a Toxic Release Inventory (TRI), which is a mandatory report on the amount of chemicals emitted annually. This report is released to the citizens to ensure their right to knowledge and life. Numerous methods have been devised to investigate the amount of chemical emissions. There are four methods to estimate TRI emissions (Emission Factor Method; Material Balance Method; Source Testing Method; Emission Model Method). Moreover, efforts have been made to increase awareness and formulate plans to reduce chemical emissions. Despite this, the TRI method tends to underestimate and overestimate, especially due to volatile compounds. If the results of the TRI emissions are underestimated, toxic chemicals can have a negative impact on citizens. Volatile compounds are commonly used in chemical manufacturing plants, such as paint plants. In this study, a suitable method for each industrial process was suggested based on conservative estimates of multiple toxic chemical inventory method, focusing on the paint manufacturing process. In the paint manufacturing plant, storage, weighing, and mixing processes should be used emission model method to estimate TRI. In the reaction process, TRI must be estimated by the source test method. In the transfer process, the emission factor method should be used to estimate TRI. In the atmosphere prevention process, the emission factor method or source testing method should be used depending on the physical and chemical properties such as vapor pressure of the chemical.

Curb Heroin In Plants (C.H.I.P.): Revisiting a Mid-1970s Intervention Into Workplace Heroin Addiction Created and Led by Detroit Autoworkers.

This article analyzes archival records to revisit Curb Heroin In Plants (C.H.I.P.), a public health intervention focusing on drug dependence that was created and led by Detroit, Michigan, autoworkers during the mid-1970s. Responding to widespread heroin use in Detroit auto plants, C.H.I.P. combined methadone maintenance with counseling on and off the job to treat heroin dependence while supporting autoworkers in continuing in employment and family life. Although C.H.I.P. ultimately failed, it was a promising attempt to transcend medical/punitive approaches and treat those with substance use disorder in a nonstigmatizing way, with attention to the workplace dimensions of their disorder and recovery. I argue that revisiting C.H.I.P. speaks to current public health debates about the intersection between the workplace and harmful drug use and how to create effective interventions and policies that are mindful of this intersection. For historians, C.H.I.P. is a valuable example of the crucial role of workplace actors in the early war on drugs and of an early methadone program that was not strongly concerned with crime reduction but incorporated social externalities (specifically job performance) to measure success.

Proceedings of the first academic symposium on developing, qualifying and operating a cell and gene therapy manufacturing facility.

A significant portion of the more than 1000 candidate cell and gene therapy products currently under clinical investigation (clinicaltrials.gov) are born out of academic research centers affiliated with universities, hospitals and non-profit research institutions. Supporting these efforts are myriad academic clinical materials production facilities with more than 40 such facilities currently operational in the United States alone. In March 2018, Stanford University's Laboratory for Cell and Gene Therapy held a symposium with the leaders and staff of more than 25 similar facilities to discuss the collective experience in developing, qualifying and operating cell and gene therapy manufacturing facilities according to current Good Manufacturing Practices. Topics included facility design, construction, staffing and operations and compliance. Leaders from several institutions gave overviews of the history of development of the facilities and discussed challenges and opportunities they had experienced over the past 10-20 years of operations. Working sessions were also held to discuss specific aspects of Process Development, Manufacturing, Quality Systems, Regulatory Affairs and Business Development with all participants contributing to the discussions. We summarize here the findings of this inaugural meeting with an emphasis on best practices and suggested guidelines for operations.

Production quality and human factors engineering: A systematic review and theoretical framework.

The purpose of this paper is to systematically examine available empirical evidence on the impact of human factors (HF) in the design and management of manufacturing operations on system quality performance. A systematic review was conducted to map the linkages between the human-system fit in the design of operations systems (OS) with production quality. A total of 73 empirical studies were identified linking HF to OS performance in manufacturing. Quality risk factors included HF aspects in product design, process design and workstation design of the manufacturing OS. Quality deficits were associated with undesirable human effects of workload like fatigue and injury-related risk factors. Forty-six percent of the studies reported on efforts to improve HF in the OS with effect sizes for quality improvements reaching up to 86%. The paper documents available quality risk factors in the design of OS. It also provides a conceptual framework explaining HF-Quality linkage.

The measurement equivalence of a safety climate measure across five faultlines.

This study examines the appropriateness of comparing safety climate survey responses across multiple faultlines-hypothetical dividing lines that split a group into subgroups based on one or more attributes. Using survey data from 8790 employees of a multinational chemical processing and manufacturing company from 76 work sites nested within 19 different countries, we examined the multilevel measurement equivalence of a safety climate measure across cultural dimensions, survey languages, organizational hierarchy, employment arrangements, and work environments. As simulation studies support the faultline at the individual-level requires measurement equivalence tests that are different from the faultline at the country-level, we used multi-group multilevel confirmatory factor analyses for the Level-3 faultline, and multilevel factor mixture models for known classes for the Level-1 faultlines. The results demonstrated that faultlines can prevent safety climate measurement equivalence, which prohibits the aggregation of individual-level scores to higher levels and making comparisons across faultlines. This first study on multilevel safety climate measurement equivalence serves as both a warning to safety climate researchers and practitioners regarding the importance of faultlines and reminds us to consider the level of the faultlines when testing measurement equivalence with multilevel data.

Unraveling the organizational mechanism at the root of safety compliance in an Italian manufacturing firm.

Safety performance is recognized as the more proximal and effective precursor of safety outcomes. In particular, safety compliance significantly reduces workplace accidents and injuries. However, it is not entirely clear what role organizational factors play in determining workers' safety. The present study contributes to defining which organizational factors increase safety compliance by testing a mediational model in which supervisor support is related to safety climate, which in turn is related to organizational identification that finally is related to safety compliance. We tested our hypotheses in a sample of 186 production workers of an Italian manufacturing firm using a cross-sectional design. Findings confirm our hypotheses. Management should consider these organizational factors in order to implement primary prevention practices against work accidents.

Cardiorespiratory fitness testing and cardiovascular disease risk in male steelworkers.

BACKGROUND: The workplace has been advocated as a setting to perform cardiovascular disease (CVD) risk assessments. These risk assessments usually focus on traditional risk factors rather than cardiorespiratory fitness (CRF) despite established associations between CRF and CVD. The lack of guidance on interpreting health-related CRF values has been suggested as a barrier to utilizing CRF in practice. AIMS: To assess the merits of CRF testing in the workplace and explore whether a CRF value identified male individuals above the recommended threshold for further clinical investigation. METHODS: Cross-sectional analysis of male steelworkers from Carmarthenshire, South Wales, UK who completed a workplace-based CVD risk assessment with an added CRF protocol based on heart rate responses (Chester Step Test). Receiver operating characteristic (ROC) analysis was undertaken to explore the possibility of a CRF value to identify individuals at an increased 10-year risk of CVD (QRISK2 ≥ 10%). RESULTS: There were 81 participants. ROC analysis revealed that a CRF level of 34.5ml/kg/min identified those individuals above the ≥10% QRISK2 threshold with the best sensitivity (0.800) and specificity (0.687) to discriminate against true- and false-positive rates. Further analysis revealed that individuals with either 'Average' or 'Below Average' CRF would be five times more likely to have a 10-year CVD risk above the ≥10% QRISK2 threshold than individuals with an 'Excellent' or 'Good' level of fitness [OR 5.10 (95% CI 1.60-16.3)]. CONCLUSIONS: This study suggests CRF assessments are a useful addition to a workplace CVD assessment and could identify male individuals at increased predicted risk of the condition.

An investigation of safety climate in OHSAS 18001-certified and non-certified organizations.

Many organizations worldwide have implemented Occupational Health and Safety Assessment Series (OHSAS) 18001 in their premises because of the assumed positive effects of this standard on safety. Few studies have analyzed the effect of the safety climate in OHSAS 18001-certified organizations. This case-control study used a new safety climate questionnaire to evaluate three OHSAS 18001-certified and three non-certified manufacturing companies in Iran. Hierarchical regression indicated that the safety climate was influenced by OHSAS implementation and by safety training. Employees who received safety training had better perceptions of the safety climate and its dimensions than other respondents within the certified companies. This study found that the implementation of OHSAS 18001 does not guarantee improvement of the safety climate. This study also emphasizes the need for high-quality safety training for employees of the certified companies to improve the safety climate.

A model for developing job rotation schedules that eliminate sequential high workloads and minimize between-worker variability in cumulative daily workloads: Application to automotive assembly lines.

The aim of study is to suggest a job rotation schedule by developing a mathematical model in order to reduce cumulative workload from the successive use of the same body region. Workload assessment using rapid entire body assessment (REBA) was performed for the model in three automotive assembly lines of chassis, trim, and finishing to identify which body part exposed to relatively high workloads at workstations. The workloads were incorporated to the model to develop a job rotation schedule. The proposed schedules prevent the exposure to high workloads successively on the same body region and minimized between-worker variance in cumulative daily workload. Whereas some of workers were successively assigned to high workload workstation under no job rotation and serial job rotation. This model would help to reduce the potential for work-related musculoskeletal disorders (WMSDs) without additional cost for engineering work, although it may need more computational time and relative complex job rotation sequences.
